[one-users] Opennebula node (CentOS, Xen host) saying Error executing collectd-client.rb when creating a host.

Tue Jul 15 04:50:46 PDT 2014

Hello, I am facing a problem while creating an host on opennebula.
I followed the official documentation and achieved it in the past, on 
the very same machine 
(http://docs.opennebula.org/4.6/design_and_installation/quick_starts/qs_centos_xen.html#qs-centos-xen) 
without having this problem.

After following this doc, I created ssh keys on the frontend and copied 
them on the node (yes, I can connect from the frontend to the node via 
ssh using oneadmin's login without having a password prompt), then I 
edited Xen's configuration in order to enable NAT (my server provider 
has MAC filtering routers).

Now, more about this error, this is what /var/log/one/oned.log says on 
the frontend's server:

    [oneadmin at GeorgeOrwell .ssh]$ tail -f /var/log/one/oned.log

After facing this, first yesterday (then I formatted today, just in case 
and faced the same problem on a fresh install), I asked on IRC and 
jfontan asked me to try this:

    bash -x /var/tmp/one/im/run_probes xen4 /var/lib/one//datastores 4124 20 4 MarieCurie.hubu.eu

Which gave this output:

    + exit 134

I must admit that I'm quite lost here (and frustrated, since it worked 
on this very same machine last week but I decided to format since I 
played around a bit with it...) and have no idea about what could cause it.

Any help would be appreciated, thanks in advance and have a nice day.
